Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a data set is bimodal, how many modes does it have?
A
1
B
2
C
3
D
4
Explanation: 

Detailed explanation-1: -Literally, a bimodal distribution has two modes, or two distinct clusters of data.

Detailed explanation-2: -The modal class shouldn’t be used as a measure of central tendency, but finding two modes gives us an indication that there could be two distinct groups in the data that should be analyzed separately.

Detailed explanation-3: -In a dataset with a bimodal distribution, two mediums are not possible. Since there can only be one median and two modes in a bimodal distribution, the mode is what matters rather than the median. We can never have two medians since the data always includes a single median value and a single mean value.
